Answer:
Three times the difference of nine and a number.
Let the unknown number/variable be = h
The difference of 9 and the number is written as [tex]9-h[/tex]
And three times this value (Three times the difference of nine and a number) is written as:
[tex]3\times(9-h)[/tex]
Now we have to tell the value of the expression when h = 5 :
So, putting h=5 in the expression.
[tex]3\times(9-5)[/tex]
[tex]3\times4[/tex]
= 12
So, The value of the expression when h = 5 is 4.
